On whose watch did Berkeley's hidden deficits grow? A factual tenure ledger · figures inflation-adjusted where noted · sourced below.
The fourth dimension of a deficit is time. Berkeley's visible ~$29M gap is the tip; underneath it sit decades of deferred deficits — unfunded pensions, retiree health, and a capital backlog — pushed down the road. This ledger asks one disciplined question: during whose tenure did each of these grow? No causal verdict beyond what the record supports.

Mayor is one vote of nine — but sets the agenda and controls the supplemental "Mayor's Budget" recommendations each cycle. Confidence: High (roster), and that agenda-setting power is the basis for weighting the mayor's responsibility above a single council vote.
Hidden deficit #1 — Pension + retiree health (OPEB)
Combined unfunded liability, inflation-adjusted, from the City Auditor's financial-condition report:
FY2012$567.4M
FY2013$666.2M
FY2014$723.9M
FY2015$623.4M
FY2016$685.8M
FY2017$723.0M
FY2018$743.6M
FY2019$721.6M
FY2020$787.2M ← peak
FY2021$773.1M
Bates eraArreguín era
Grew 36% over the decade ($567.4M → $773.1M). It rose under Bates, and reached its peak on Arreguín's watch (FY2020). Confidence: High (Auditor figures, inflation-adjusted).
Honest caveat: CalPERS contribution rates and discount-rate changes are partly outside the City's control — the Auditor says so explicitly. Pension growth is the least attributable of the three. Use it as context, not as the centerpiece of any blame claim.
Hidden deficit #2 — Capital & deferred-maintenance backlog
This is the one that lands. The infrastructure backlog data begins FY2017 — almost exactly Arreguín's tenure:

→Ishii
~$1.8B (range $1.65B–$2.5B)
The backlog more than doubled FY2017→FY2021 ($524M to $1.2B), entirely within Arreguín's tenure, and has since climbed toward ~$1.8B. This is the strongest "on whose watch" fact you have: it is large, recent, and squarely inside one administration. Confidence: High for $524M→$1.2B (Auditor); Moderate for current ~$1.8B (press/staff range, estimates vary).
The visible deficit handed forward
FY2021: City faced a $40M General Fund deficit and made "difficult decisions to balance the budget." (Arreguín era)
FY2027: a $29.2M structural deficit — now the inherited problem — with 138 proposed layoffs, service cuts, and a sales-tax measure. The crisis surfaced as Arreguín left office.
…and this is even under the Mayor's own budget
Berkeley's process gives the mayor a supplemental "Mayor's Budget" — direct authority to shape each cycle's adopted spending — and Arreguín campaigned on "Budget Accountability." The backlog still tripled and the structural gap still grew. The deterioration didn't happen around the mayor's budget; it happened through it.
Confidence: High that the supplemental Mayor's Budget and "Budget Accountability" branding existed; the point is that the tools to prevent this were in the mayor's hands.
The defensible bottom line
Stated precisely:
On whose watch (fact): Berkeley's capital backlog more than doubled and its pension/OPEB liability hit its peak during Jesse Arreguín's mayoralty — the same years he controlled the supplemental Mayor's Budget — and the structural deficit now forcing layoffs surfaced as he left.
Timeline (interpretation): Much of the deficit's growth accumulated under the prior administration — though the Mayor's-Budget role is one vote plus persuasion (see The “Mayor’s Budget”), not a formal power, and the council acts collectively.
What it is not: a claim that any single official "caused" a precise dollar of unfunded liability. Pension drift is partly exogenous; council acts collectively. Don't overclaim — the on-whose-watch timeline speaks for itself.
